Abstract

The title compound, [HP(CH3)3][IrCl4{(H3C)3P}2], consists of a tri-methyl-phospho-nium cation and a tetra-chlorido-bis-(tri-methyl-phosphane)iridate(III) anion. The anion has an octa-hedral arrangement of ligands, with the tri-methyl-phosphane groups occupying trans positions. The Ir(III) atom sits on an inversion center with one P(CH3)3 ligand and two chloride ligands in the asymmetric unit. The tri-methyl-phospho-nium cation is disordered about a twofold rotation axis. The title compound is the first structurally characterized tetra-chlorido-bis-(phosphane)iridate complex.
